It looks like this tooth (or, rather, the root that my regular dentist couldn't extract, and that I have to go to an oral surgeon to have removed) is infected. Again.

Luckily, I am now on antibiotics. And so far, OTC ibuprofen seems to kill the pain (if I gets worse, I still have some of the prescription ibuprofen from the last time this little bugger got infected).

I will be very glad to be rid of this thing come Tuesday - it's been nothing but trouble for quite a while.
